Down out of the heights they swept at a rapid pace. A few moments later they had burst through the film of clouds and once more the lake was below them in clear view.
Suddenly Ned pointed to something on the water and cried:
"Look, Tom! Look! A motor boat in some kind of trouble! She's sinking!"

COALS OF FIRE
Tom Swift saw the craft almost as soon as did his chum. It was rather a large-sized motor boat, quite some distance out from shore, and there was no other craft near it at this time. From the quick, first view Tom and Ned had of it, they decided that a party of excursionists were on a pleasure trip.
But that an accident had happened, and that trouble, if not, indeed, danger, was imminent, was at once apparent to the young inventor and the other occupant of the swiftly moving airship.

"Help! Help!" came the impassioned appeals, floating up to Tom and Ned.
